PAPER-REGISTERING MECHANISM.

SPECIFICATION forming part of LettersPatent No. 652,169 dated June 19,1900.- Application filed October 24, 1899. Serial No. 784,623. (Nomodel.)

To all whom it may concern:

Be it known that I, TALBOT O. DEXTER, of Pearl River, in the county ofRockland, in the State of New York, have invented newand usefulImprovements in Paper-Registering Mechanism, of which the following,taken in connection with the accompanying drawings, is a full, clear,and exact description.

This invention relates to an improvement in mechanisms employedinconnection with paper-folding machines and analogous machines for thepurpose of automatically and accurately registering the sheets of paperpreparatory to folding or otherwise operating on the same; and theinvention has special reference to the class of paper-registeringmechanisms in which the registering instrument proper is equipped with atongue or point adapted to enter a slit provided in the sheet for thatpurpose.

The object of my present invention is to provide more efficient meansfor opening the slit in the paper to facilitate the entrance of theregistering-pointinto said slit; and to that end the invention consistsin the novel construction and combination of the component parts of theregistering mechanism, as hereinafter fully described, and set forth inthe claims.

In the annexed drawings, Figure 1 is a vertical longitudinal section ofa portion of a paper-folding machine equipped with my improvedpaper-registerin g mechanism. Fig. 2 is a reduced plan View. Fig. 3 isan enlarged plan view of the registering mechanism. Fig. 4 is anenlarged vertical transverse section on line Y Y in Fig. 1. Fig. 5 is anenlarged detached plan view of the slit-opening bridge and the bed whichimparts a further advance movement to the sheet to be registered; andFig. 6 is a vertical longitudinal section of a portion of afolding-machine, illustrating a modification of the paper-registeringmechanism.

Referring to the drawings, A represents the main frame of thepaper-folding machine.

B ]3 denote the usual folding-rollers.

a a are the traveling tapes,wl1ich convey the sheets of paper into themachine, and 1 1 are the longitudinal bars, which support the por tionof the sheet beyond the folding-rollers;

O designates the folding-blad e, which tucks traveling tapes.

i the aforesaid blade 0.

the sheet between said folding-rollers, and D is the feed-roller, uponwhich the tapes a a run, over which roller are located the droprollers DD, which press the sheet upon the All of said parts are arranged tooperate in the usual and well-known manner.

E represents the front stop or end gage, against which the advance edgeof the sheet is brought when fed into the machine. Said gage is made toalternately move part way toward and from the folding-rollers B Bby'means of a rock-shaft F, having depending from it arms F F, the lowerends of which are connected to longitudinal bars G, upon which theaforesaid gage rides and is adjustably secured in its position by meansof sore wrods b, passing through nuts 0 on the gage and journaled inbrackets d, attached to the bars G. On the ends of the screw-rods b aresecured worm-gears H, which mesh with cor responding gears H, secu redto a transverse shaft e, which is journaled in ears g 9, formed on thebrackets d. The end of the shaft is provided with a hand-wheel h bywhich to turn it, and thereby turn the screw-rod b, which moves the gageE to the desired position in relation to the folding-rollers B B toaccommodate sheets of different lengths. The rock-shaft F receivesmotion from a lever I, which is attached thereto, and isoscillated bymeans of a rotary cam I, secured to a shaft J, journaled on the mainframe, which latter shaft receivesits motion, preferably from one of thefolding-rollers B, either by a chain, belt, or gears, as indicated bydotted lines at as in Fig. 2 of the drawings, although the same may beoperated otherwise. The aforesaid bars G ride-upon, rollers e' e',journaled on a transverse shaft j, supported in posts 7t is, mounted onthe frame A.

The purpose of my improved paper-registering mechanism is toautomatically and accurately adjust the sheet to bring'a predeterminedline of folding directly over the bite of the folding-rollers B B beforethe sheet is introduced between said rollers by There being tworegistering instruments employed and located at opposite sides of thecentral line of travel of the sheet of paper, as is well known, each ofthese registering instruments is operated by the following mechanism,towit: A bracket A is mounted on a stationary cross-bar B, preferablydovetail-shaped in cross-section and extended across the machine andsupported on the aforesaid posts 70 70 on the frame A. From said bracketextends rearwardly or toward the folding-rollers a hori zontal bar 0,which is shaped dovetail in cross-section or otherwise formed with alongitudinal guide and supported at one end on said bracket and at theopposite end on across-bar E, mounted on suitably-supported posts on m.To the side of the bar 0 are pivoted the bell-crank levers n n, and tocorresponding arms of these levers is pivotally connected a horizontalbar G. The other arms of the levers n n are connected by means of a rod0, which causes said levers to operate in unison and to raise and lowerthe bar G in parallel planes. One of the latter arms is extended inlength and is connected, by means of a rod 19, to the upper end of anarm q, rigidly secured to a transverse rock-shaft 0, whereby saidleversare oscillated. The shaft 1" is journaled at its ends to stationarybrackets J J, mounted on the frame A, and passes through the aforesaidbrackets A and receives its motion from a lever 8, depending from saidshaft and oscillated by means of a rotary cam A secured to the aforesaidshaft J. The rod 19 is screwthreaded at its connection with the arm qand is provided with nuts t t at opposite sides of the arm, whereby thedistance between the points of connection of the rod 10 can be varied tocause the levers n n to carry the bar G at the desired elevation abovethe plane of the paper-supporting bars bb. A vertical plate a isformed*with a horizontal projection 19, and through this projectionpasses a set-screw d, which bears upon the rib 0, formed on the side ofthe bar G, and thereby supports the plate a in a suspended andvertically-adjustable position. To the lower end of said plate isattached the tongue 6', which by engagement with a slit in the paperregisters said paper. By the aforesaid vertical adjustment of the platea the tongue 6 is made to bear with the requisite pressure upon thepaper to effect the aforesaid register. The tongue 6 projects rearwardlyfrom the plate a and is located in the path of the slitted portion ofthe sheet, so as to enter the slit, as hereinafter more fully described.The plate a slides in a vertical guide f, formed in a block g, mountedlongitudinally adjustable on the bar 0', which adjustment iseifected bymeans of a screw-rod h, journaled in a block i, adjustably secured tothe bar 0 by a set-screw. Said rod 72. passes through a screw-threadedear j, formed on the block g. Said adjustment is provided for thepurpose of setting the tongue-e in the required position according tothe location of the slits provided in the sheets.

1 13 represents a bed consisting of a pad of rubber or other suitablematerial upon which a portion of the delivered sheet rests. Said bed iscarried on alongitudinally-reciprocating plate a which receives itsmovement from the aforesaid gage E, to which it is secured, preferablyby means of an L-shaped plate b clamped adjustably onto the plate a. bymeans of a bolt 0 passing through the horizontal portion of the plate 19and through a longitudinal slot 3 in the plate a and attached to awasher 4E and provided with a nut 5 on its end. The plate a slides inlongitudinal grooves or guides 01 11 provided in the edges of the bars1 1. The bed B carried onthe plate a serves, with the aid of thesheet-depressor hereinafter described, to obtain a frictional hold onthe sheet to impart a secondary advance movement to the sheet after thesheet has been arrested by the gage E, as will be shortly more fullyexplained.

d is a vertically-disposed coil-spring which is connected at its ends totwo pins c f projecting horizontally from the upper portion of the platea and lower portion of the block g, respectively. Said spring serves toimpart 'a downward pressure to the plate at, whose downward movement inthe guide f is limited by the aforesaid set-screw d. Saidsheet-depressor consists of a roller 9 located back of the aforesaidregistering-tongue e and journaled on a bracket 7L2, secured verticallyadjustable to the plate a by means of the attaching-screw 71 passingthrough a vertical slotj in the plate a.

In front of the tongue 6 is located a sheetlifting bridge k which issecured longitudinally adjustable to the plate a by means of a bolt Zpassing through a slot 121 in said plate and engaging the bridge. Saidbridge being in the path of the slitted portion of the sheet serves, inconjunction with the depressingroller 9 to open the slit for theentrance of the tongue 6.

The aforesaid bracket A is adjustable lengthwise of the cross-bar B toaccommodate to the width of the sheet the sheet-registering devicescarried on said bracket, which adjustment is effected by means of ascrewrod 0 which is parallel to the bar B and journaled in suitablebearings on the frame A and passes through a nut g formed on the bracketA. The rod 0 is provided with a hand-wheel o I The operation of myimproved paper-registering mechanism is as follows: The sheet of paperis conveyed into the folding-machine by the tapes a a, while the bar G,carrying the registering instrument and depressingroller 9 is in itselevated position, whereby the sheet is brought with its advance edgeagainst the gage E and is thereby arrested, said gage being in itsposition nearest the foldingrollers B B. The bar G is then dropped,whereby the tongue e of the instrument is made to bear slightly upon thesheet and the roller 9 to bear firmly thereon to press the sheet intofrictional contact with the bed B Immediately after the tongue 6 androller 9 have been brought into contact with the sheet the gage E ismoved forward, thereby shifting the bed 15*, which by the aforesaidfrictional contact with the sheet imparts a secondar advance movement tothe sheet. In this movement the slitted portion of the sheet is drawnonto the top of the bridge k which opens the slit and facilitates theentrance of the tongue e. The rear edge of the slit then coming incontact with the heel of the aforesaid tongue arrests the furtheradvance movement of the sheet and accurately registers the same. The barG is then raised, whereby the tongue e lifts the slitted portion of thesheet to prevent the slit from being caught on the bridge and tearingthe same when the sheet is Withdrawn from the tapes a (L by thefolding-blade C, which descends and tucks the sheet between thefolding-rollers B B in the usual and wellknown manner. After the sheethas been withdrawn the gage E recedes, and the registering instrumentand depressing-roller being in their elevated position the next incomingsheet is allowed to pass under said instrument and roller to beregistered in the manner described.

In some cases Iprefer to support the sheetdepressing roller gindependent of the registering instrument, as illustrated in Fig. 6 ofthe drawings, in which said roller is pivoted to vertical plate 7*,which slides vertically in a block 3 mounted longitudinally adjustablein the bar 0, which adjustment is effected by means of the aforesaidscrew-threaded rod h, which engages a screw-threaded car 1 formed on theblock .9 The plate r and block 8 are provided withhorizontally-projecting pins n and 17 respectively, to which isconnected a coil-spring 10 Said spring serves to impart a downwardpressure to the plate 9*, the downward movement of which plate islimited by a set-screw .99
